CHARLES W. DEAN, OF SOUTH WAREHAM, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO EDGAR ROBINSON, OF SAME PLACE.

MANUFACTURE OF PLUMBERS HOOKS.

SPECIFICATION forming part of Letters Patent No. 279,228, dated June 12, 1883.

Application filed April 1, 1882. Renewed March 5, 1883. (No model.)

T aZZ whom it may concern.-

Be it known that I, CHARLES W. DEAN, a citizen of the United States, and a resident of South Wareham, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Hooks, of which the following is a specification.

The object of this invention is to manufac ture from band or plate iron or other metal a hook especially adapted for holding or sup- .porting gas and other pipes to the walls or ceilings of buildings.

The invention consists of a hook having a semicircular inner curve, an angular project ing heel, and divergent sharppointed shank and point of unequal lengths cut from a plate of metal; and it further consists in forming said hook by making in the plate of metal a double cut, or two single outs simultaneously, one to form theinner outline of the hook and the other to form the angular'heel and the outer edge of the point of the hook.

Figures 1 and 2 represent face views of plates of metal having the double or two single cuts shown upon them to form the hook. Fig. 3 represents the hook-in position supporting a piece of pipe.

Similar letters of reference indicate corre-,

sponding parts.

The plates A, from which the hooks are cut, are like ordinary nail-plates, prcferali-ly of much greater length than width; and said hooks B are cut from one end of a plate, so that both ends of said hooks B are pointed, as shown at a, without further cutting; but in order to produce completed hooks without further cutting .or manipulation when once they are separated from. the plate A, a double cut, or two simultaneous cuts, are made, the cut 72 extending diagonally upward at an angle of about forty-five degrees from one edge, a, of the plate A to about the middle thereof to fashion or shape the outer edge of the shank of one hook, B, and the inner edge of the shank of the next succeeding one, and then curving upward in a semicircle, and then downward at an angle of about twenty degrees to the opposite edge, d, of the plate A to form the inner curve, a, of the hook and inner edge of the point thereof, while the cut f, made simul- 5o taneously with the out 1), extends from the cut 8 b at the point where the diagonal portion thereof merges into the semicircular portion thereofto the edge d of the plate A in a broken or irregular line, as shown at 9, Fig. 1, or in 5 a slightly-curved line, as shown at h, Fig. 2, nearly at right angles to the diagonal portion of the cut 12, thereby separating from the plate A and hook-blank a waste piece or segment, 0, of metal, thereby forming the outer edge of the hook-point m, and also a projecting angular heel, it, having a flattened face, Z, which latter is nearly at right angles to the shank n, and is designed to receive the blows of the hammer or other tool used in driving the said 6 hook in place for holding in its inner curve a gas-pipe, D, or the object, as shown in Fig. 3.

In forming the hooks B, I do not confine myself to making the cuts in the metal plate A at the angles herein shown, as the angles may vary according to the inclinations desired to be given to the shank and point.

I am'aware of the patent of E. P. Gleason, dated August 8, 1865, No. 49,257, and I do not claim cutting from a bar or plate a blank 7 5 which has afterward to be bent and hammered to form a plumbers hook, my invention differing therefrom in producing a finished cut hook, which requires no treatment after being cut from the bar or plate.

What I claim as new is- 1. As an improved article of manufacture, a finished cut plumbers hook.

2. The hook herein described, having a semicircular curve, a, angular heel 7c, and 8 5 arms m at, having beveled ends a, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 18th day of March, 0 A. D. 1882.

CHARLES W. DEAN.

JAMES G. SPROAT, THOMAS M. RYDER.
